How we handle new build mastic in Shelvin
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. Typical jobs include shower seals failing in the first year or two and joints pulling apart as timber shrinks, on kitchens, bathrooms & en suites and plot handovers.
Older homes in small places like Shelvin often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work comes with a 12-month guarantee.

Shelvin: your questions answered
Can you help a landlord with a rental near Shepherds Well station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Is Shelvin in your area for new build mastic?
Yes, Shelvin is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common. Poor preparation at handover adds to it.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Where a wall is exposed, as many are in small places like Shelvin, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When something else is needed
In fairness, some problems need a different trade:
- A tray or bath that is not properly supported, until it’s fixed
- Structural cracks in walls or ceilings
- Cracked trays, tiles or worktops
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Signs you need new build mastic in Shelvin
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
Look out for these signs:
- Cracked sealant around new window and door frames
- Second-fix sealing on new plots
- Leaking shower tray seals in a new home
- Untidy sealant flagged on a snagging list
For new homes near Shepherds Well station, it’s worth checking the sealant early, while snags are still fresh.
What to look for in a quote
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- How much experience the applicator has
- The length of the guarantee

- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
